“Perfect, as we expected.†Lu Weijian, chief designer of AVIC helicopters of AVIC, said in an interview that we will arrange all the flight test verification work and bring it to market as soon as possible. According to reports, the AC352 adopts a conventional aerodynamic layout, double-engine, wide-body, and the first three-point retractable wheeled landing gear. The cabin space meets the needs of 14 to 16 passengers, and the main components including the engine are localized. . advanced technology According to the relevant person in charge of AVIC, the AC352 helicopter is a 7-ton civil helicopter developed in accordance with the requirements of airworthiness regulations. It adopts a variety of mature advanced technologies such as 4-axis digital automatic flight control system, and has day and night flight under visual and instrument flight rules. ability. The maximum take-off weight is 7,500 kg and the maximum range is more than 1000 km. The AC352 is also one of the safest helicopters in its class. The crashworthiness of the aircraft fuselage is higher than the airworthiness requirements. Even in the case of transmission system oil leakage, the final drive can still run for 30 minutes without oil, providing ample time for the pilot to find a suitable place to land. The AC352 is also one of the most comfortable helicopters in its class. With a cabin length of up to 4 meters, the cabin has the largest cabin interior space of the same tonnage model. It is flat and barrier-free, providing ideal seating layout and first-class comfort. Large-size portholes are perfect for all passengers. Good external view. In addition, the AC352 is one of the most environmentally friendly helicopters in its class. The machine's main blade and tail blade use a new generation of blade airfoil profile and tip shape to increase lift and speed while reducing vibration and noise. It is worth mentioning that the AC352 is one of the most economical helicopters in its class. The fuel consumption rate per kilometer of the aircraft is significantly lower than that of similar engines, which effectively improves the range capability and battery life of the AC352 helicopter. "AC352 has filled the blank of China's aviation equipment and is a new business card for China's equipment manufacturing industry." Yang Yuchang, deputy director of the Equipment Department of the Ministry of Industry and Information Technology, said in an interview. According to reports, the AC352 helicopter's rotor system and fuselage life can reach 20,000 hours, the transmission system and engine overhaul interval up to 5,000 hours, greatly reducing the cost of use. Broad market As the leader in the 7-ton medium-sized helicopter, the AC352 helicopter has covered various fields used by our civil helicopters and therefore has broad market prospects. The AC352 helicopter is a civilian helicopter developed under the principle of “one platform for multiple uses and serial developmentâ€, in accordance with the design concept of “designing one step in place and configuration according to user requirementsâ€. It can be customized according to the needs of users, such as offshore transportation, search and rescue, general transportation and other configurations. It can be widely used in many fields such as offshore transportation, search and rescue, and police enforcement. The AC352 helicopter's offshore transport configuration has the most spacious cabin in the same tonnage model, enabling a comfortable layout with no more than one seat distance per window from the passenger. It is also possible to perform tasks in different ranges by adjusting the number of passengers. In addition, the configuration has a maximum passenger capacity of 18 passengers and can be transported for short distances within 194 km. The aircraft search and rescue configuration has the farthest range and voyage in the same tonnage model, and can load more than 2 tons of fuel. The cabin has direct access to the rear cargo hold; the flat, barrier-free cabin is easily accessible for emergency medical services and search and rescue operations. The mission system of this configuration includes radar, directional instrument, digital real-time map and automatic identification system, which fully meets the search and rescue needs under the harsh weather conditions of land and sea. The AC352's universal transport configuration and VIP and business configuration are derived from the oil and gas platform configuration, and can be fitted with large and comfortable leather seats, soundproof interiors and double-deck cabin glazing. In addition, the cabin seats with a quick-fit snap-on design can be completely removed in 30 minutes, quickly changing from a passenger configuration to a cargo configuration. According to reports, the AC352 helicopter will speed up the airworthiness evidence collection work and strive to be put on the market as soon as possible. At the same time, we will do a good job of improving and renovating, realizing the serial development of products and achieving commercial success. The company will be fully operational support, allowing users to enjoy after-sales service in the full value chain. China's civilian helicopters form a 2-ton platform represented by AC311, a 4-ton platform represented by AC312, a 7-ton platform represented by AC352 and a 13-ton platform represented by AC313. The relevant person in charge of AVIC said that in the future, new civilian helicopters such as AC311A, AC322, AC312E and AC312C will be launched, and heavy-duty helicopter projects will be developed as planned, and high-speed helicopters and tilt-rotor helicopters will be pre-study for domestic and foreign users. Come to more excellent products.
